To all whom it may concern:

Be it known Vthat I, WILLIAM HENRYV V be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure 1, a view in side 'elevation of my improved gas-drier applied to an ordinary generator; Fig. 2, a detached plan viewof the gas-drier; Fig. 3, a view thereof in vertical section; Fig. 4, a' detached sectional view of the bottom plate; Fig. 5, a detached broken sectional view of the lower end of the inside shell, showing the bayonet-gl oint groove formed therein; Fig. 6, a detached sectional view of the guard-tube.

My invention relates to an improved gasdrier for use in drying acetylene gas, the ob-V ject being to produce a simple, convenient, and effective device for removing from acetylene gas all traces of the moisture associated with 1t as it leaves the generator. i

Although primarily designed to be used as an attachment for generators carried for lighting pur oses on automobiles, my improved gasrier may of course be used in any situation where such a device is needed.

With these ends in view my invention consists in a gasedrierk having certain details of construction and combinations of parts, as will be hereinafter'des'cribed, and pointed out in the claims.

For the better illustration ofmy improved device VI have shown it in conjunction with a generator which may be regarded for my present purpose as typical of the entire class and consisting of a water-tank 2, connected bypivoted coupling-rods 3 and thumb-nutsLl with a case 5, containing a carbid-chamber 6, an ash-receiving chamber 7, and a screen 8, separating these chambers. A perforated tube 9,' entering the chamber V6, receives water from theA tank 2 through a pipe 10, controlled by' a valve 11, whereby the water is fractionally supplied from the tank 2 thro ugh thepipe 10 and perforated tube 9 to the carbid-.chamber 6. Y A

The generator iabove described is such a generator as is carried by automobiles for the generation of the gas required for lighting. As herein shown, my improved gas-drier is constructed with particular reference to being applied to one of the two coupling-rods 3 of thegenerator. It may, however, be attached thereto in any other way, or, Vif preferred, it may have no connection therewith other than through the tubes through which it receives the gas to be dried and enriched therefrom. As shown, the drier is provided with two nipples 12 for the application of two tubes 13, leading to them from corresponding nipples 14, located upon the top of the tank 2. However, one tube and one nipple on the drier and one tube and one ni ple on the generator will suffice. The said) nipples 12- are located upon the opposite faces of a cap 15, which is internally threaded for being screwed upon the threaded upper end of a tube 16, which I shall hereinafter call the gas-supply tube. Ports 1.7 in the ca 15 register with corresponding ports 18 in t e upper end of the said tube 16, into which the gas is thus led from the nipples 12. The said tube 16 is encircled near its upper end by a washer 19, which might, of course, be made integral with the tube and form an annular flange. This washer 19 is set down flush into a circular plate 20, to which it is secured by brazing or otherwise, whereby the tube is secured in place. The plate 20 is set into the upper end of a cylinder or outer shell 21, in which it is screwed or with which, if preferred, it may be made integral, the said plate and shell forming what, for convenience, I shall call the outer case or body``of the device. This outer case or body is, in eHect, a cup turned bottom up.

The gas fed into the tube 16 passes out through perforations 22 in its lower end into a guard-tube 23 larger in diameter than it is.

This guard-tube has perforations 24 in its lower end and secured by soldering or otherwise to the center of a perforated diaphragm 25, which divides the inner shell or cup 26 into a carbid-chamber 27 and an ash-chanel ber 28, this cup being formed, as shown, with a shoulder 29 for the diaphragm 25 to rest upon. Also, as shown, the guard-tube 23 is closed at its lower end by a bottom plate 30 but this may be made integral, if preferred. The 'lower end of the shell 26 is closed by a IOO removable bottom plate 31, having concentric flanges 32 and 33 upon its upper face. The said flange 32 is adapted in diameter to fit snugly within the shell 26, to which the 5 plate is removably secured by a bayonet-slot lock comprising a small projection 34, struck out from the flange and coacting with a shallow groove 35, formed in the inner face of the lower end of the shell 26. To permit the ro plate to be turned as required for removing it from and replacing it in the shell, it is provided with a depending finger-piece 36. The flange 33 is formed with external threads taking into corresponding threads in the lower end of the shell 21, whereby the plate 3 1, and

hence the cup of which it forms a part, is secured to the case or body of the device. The upper edge of the shell comes to a bearing upon a packing 37, placed against the inner zo face of the plate 20. The upper end of the guard-tube 23 also comes to a bearing upon this packing. The upper end of the shell 23 is formed with holes 38, leading into an annular chamber 39, formed between the shells 21 z 5 and 26. From thischamber the gas enters a nipple 40, containing a strainer 41. If preferred, of course, the device may be provided with two or more nipples like the nipple 40. As shown, also, the shell 21 is provided with 3o straps or clips 42, by means of which the device is mounted upon the coupling-rod 3. After the carbid-chamber 26 has been filled with carbid and the cupof the device is re- -stored to the body thereof the guard-tube 23 3 5 sleeves over, as it were, the gas-supply tube 16, which is thus protected from the carbid. But for the guard-tube the gas-supply tube would have to force its way through the carbid, which would be likely to clog its open- 4o ings 22.

In the operation of the device the gas generated in the generator passes from the nip-l ples 12 into the gas-supply tube 16, from which it passes into and through the guardtube 23 and thence into the carbid-chamber 27, charged with carbid, which having a very great aliinity for moisture extracts the same from the gas, which it leaves perfectly dry. The dry gas then passes throughthe perfora- 5o tions 38 in the shell 26 into the chamber 39 and thence through the nipple 40, from which it is conducted in any convenient way to the lamps. The moisture extracted by the carbid from the gas slowly decomposes it with the production of a small quantity of acety- Y lene gas, which is added to the volume of gas going through the drier. As the carbid is decomposed its powdery ashes drop through the diaphragm 25 into the chamber 28, from 6o which they are removed by the removal of :the doubly-flanged bottom plate 31. The operation of my improved drier is virtually 1 the straining of acetylene gas through carbid, which extracts from it its moisture, which in turn decomposes the carbid with the producnot limit myself to the `exact construction.
